I IMPROVEMENT lN GRAIN-DRILLS.

To all whom it may concern Be it known that I, PETER State of Illinois, have made certain new and useful Improvements in Grain-Drills and I do hereby declare the following to be a full and correct description thereof, reference being had to the accompanying drawings, and fo the letters of reference marked thereon.

This invention relates to machines for planting or drilling wheat and other grain.

It is known that in drillingseed-grain, in? order to reduce the resistance at the iiukes or shoes, and to prevent thesamefrom being thrown out of ground inheavy, weed y, or clodfi ded soil, it becomes advantageous to move thev flakes from a straight to a zigzag line, and thus obtain greater clearance between the same. This is usually performed by hand, actuating a lever, or similar means to move the flukes.

In order to accomplish said movement more nearly in. accordance with the nature of the soil than hitherto done by the. devices aforesaid, the nature of this invention is, first, in such arrangement and adjustment of the flakes or shoes of a grain-drill to and with the frame that the line of setting assumed by the flakes shall be in accordance with the resistance of the soil, and that said flukes shall thus be to a great degree self-setting.

In order, furthermore, to make my said drill applicable to ground in which the soil-resistance is insufficient to move the flukes, the nature of this invention is, secondly, in aiding the movement of the flukes by the draft-power of the team propelling the drill.

To enable those herein skilled to make and use my said improvement, I will now more fully'describe the same, referring to the accompanying Figure 1 as a sectional elevation, to Fig. 2 as a plan, and to Fig. 3 as a rear view of my said drill in its usual form, such parts as are immaterial in this description being omitted.

I arrange the frame A, of the usual form, supported upon the wheels B,

The draft-team is attached by proper single or double tree to the pole or tongue G, which is guided on the frame A by the strap 0, and secured to the frame by the pin 0 in the stirrup D.

J. Scnnir'r, of Carlinville, in the county of Macoupin and -At the forward end of the frame A, I arrange'therock-bar E, pivoted in proper bearings at e. The forward ends of the drag-bar F are attached alternately to the top or bottom edge of said bar.

The flukes or shoes G are connected with the drag-bar in the usual manner, and said flukes have the chains 9, connecting with the lift-bar H, by which the flukes may be raised out of ground. For this purpose the bar H is pivoted to the frame A at h, so that by throwing said bar up the chains 9 wind about or on said bar, and thus lift the flukes.

To hold the rock-bar E in the position assumed, (and to move the same, whenrequireth) I arrange thereon the forked lever I, passing up into the slots of the slide K, resting on the tongue C.,

A springlever, L, secured to the tongue,

' has the tappet l projecting into any one of the holes 7c of the slide K, thus detaining said slide and the lever I and rock-bar E.

If the drill is operating with the tlukes Gin a straight line, and the flakes are observed to becameclogged, or the resistance therefrom seems excessive, the operator raises the tappet 1 out of the slide K by depressing the lever L, thus releasing the rock-bar E of its detent, and the flukes- G will then be free to form their own setting or line in accordance with the resistance of the ground. If the line has been formed, the operator may retain the flukes therein, as may be desired, by releasing the lever L, so that the slide K will be held as at- It is plain that by the manner of attaching the flukes by this drag-bar to the. rock-bar E, in forming a zigzag line, one part (usually onehalf) of said flukes moves forward, and the other half part moves back, this latter movement being impelled by the resistance of the soil, but the former movement being against said resistance.

In order that said movement may bepossible, it may be advantageous to give to the flakes which drop back a greater leverage inthe attachment 'of their drag-bars to the rock-bar E than to the flukes moving forward 5 but in all cases, for the purpose of insuring the movement aforesaid in the varied classes of soil, and to secure a return movement of the flukes,
